Effect of lead acetate (400 ppm) was investigated by administration in drinking water for six weeks in broiler chicks. The functional activity of macrophages assessed by nitroblue tetrazolium (NBT) reduction test indicated a significant decrease in number of functional macrophages in birds given lead acetate. The mean NBT positive cells were 35.60 ±1.22 and 21.20 ± 1.04% in control and treated birds respectively.
